Abstract

During too long electrocrystallisation of dendritic copper on cathode rods the surface deposit lay restructures from branched dendritic one to rough globule scrabs. Overpotential boundary conditions are determined (η_bound) by means of chronogalvanometry method in series of constant cathodic overpotentials. This overpotential (–0,55 V) corresponds the change on control nature on deposit growth front (from mixed to pure diffusion one).The duration of continuous deposit crystallization which corresponds to η_bound, achievement forms 1,6–1,8 hour against technological 2 hours.

Abstract

Reducing smelting of preliminarily roasted copper sulfide concentrate even without addition of dope collector-phase, allows effectively extract copper and precious metals to the bottom phase (blister copper). Experimental investigation of impact of some parameters of smelting, such as concentrations of SiO₂, CaO, Na₂O in slag and temperature to the distribution of gold and silver was conducted, using charcoal as reductant. Obtained results show, that optimal slag composition in case of minimization of precious metals losses is: Na₂O 6–7 %, CaO — 12–18 %, SiO₂ — 32–36 %. Optimal process temperature is 1573 K.

Abstract

For power consumption decrease for alumina production the technological scheme should be optimized to satisfy thermodynamic and to technology requirements. The energy effervescive is relative characteristic of thermodynamic perfection of process. Determination of energy effervescives of heat-consuming system elements in alumina production has allowed to reveal the processes characterizing by the high inconvertibility, to plan ways on reduction or liquidation of this inconvertibility. The maximum effect is provided by schemes with high degree of regeneration of reacting heat flows.

Abstract

Kinetics of lepidolite and sulphuric acid interreacting is investigated. The amount of apparent activation energy of lepidolite and sulphuric acid reactions is determined: E_app = 7,6 kJ/mol. It is possible that interreacting of mechanically reactive beryl with sulphuric acid is limited by the acid molecules diffusion rate to the response surface through the layer of resultants.

Abstract

The silver halogenide crystals transparence from visible to far-infrared region, nonhygroscopicity, nontoxicity and high plasticity are the great advantages in front of other optical materials. It is the kind of material that determines the technical characteristics of the basic optical materials and fiber-optical elements for different purposes. The radiation-resistant and transparent in 0,40–45 region new AgBr—TlI, AgCl_хBr_1–х crystals, including those, that are alloyed with TlI, were elaborated. The growth technologies, including unconventional multicomponent homogeneous single-phase charge and single crystals growth on the new KPC-01 device, were developed. On the base of theoretical calculations there was simulated the structure of the new defective crystals, which are the solutions of substitution. The unique crystals properties, plasticity, nonhygroscopicity, and the wide range of transparence in generally, provide the production of single- and multimode light guides of the new generation for middle and far-infrared regions.

Key words

Abstract

Results of experiments on metal chip crushing and other light scrap at industrial rotary jet mills developed in LLC «New technologies – engineering» (St. Petersburg) are resulted. Problems of high efficiency mills creation and maintenance of crushing in the inert media are solved. The wide spectrum of metals is investigated. Possible spheres of powders application are analyzed. The paper shows, that it is possible to produce from a powder the materials with porosity of ~50 % with use of electropulse technology.

Key words

Scrap metal, metal chip, metal powders, mechanical grinding, rotary jet mills, porous metals, electropulse technology of metal chip briquetting.

Maksimov E. A., e-mail: maksimov50@mail.ru, «Intray»

Abstract

The new self-regulatory mechanism of process of asymmetrical cogging is offered. Thus capillary tension on borders of deformation zone and land length with opposite friction forces are regulators of gage and bar drawing, characterizing the geometrical sizes accuracy.
Experimental data of the self-regulatory mechanism of process of asymmetrical cogging on longitudinal, cross gage interference and bar flatness is listed.

Key words

Asymmetrical cogging, bar drawing, geometrical sizes, deformation, gage interference.
